Vector $\mathbf{u}$ has a magnitude of 4 and a direction angle of $30^{\circ}$. Write the component form of this vector. I don't understand where I need to even start at.

Draw a right triangle with hypoteneus of 4. We can write the vector with magnitude 4 at angle 30° as the sum of the vectors represented by legs of this triangle. You want to find these vectors using right triangle trig.
Basically a the vector you are given has an x and a y component. You have to find them using right triangle trig given that the hypoteneus is 4 and the angle is 30°
